Kua tāruatia ki te papatopenga
x\times 2=\left(x-1\right)\times 3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara 0,1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x-1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-1,x.
x\times 2=3x-3
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 3.
x\times 2-3x=-3
Tangohia te 3x mai i ngā taha e rua.
-x=-3
Pahekotia te x\times 2 me -3x, ka -x.
x=3
Me whakarea ngā taha e rua ki te -1.
Ngā Tauira
whārite tapawhā
